Excitation of forced modes in the dielectric disk resonator-diffraction grating system

Abstract

In this work the strip-like diffraction grating influence on the spectrum of “whispering gallery” modes of the disk dielectric resonator was studied experimentally. The conditions of single-mode excitation in a wide frequency range had been defined.
